The outcomes of compressed spinal cord injury (CSCI) necessitate radical treatment. The therapeutic potential of neuroectodermal stem cells (NESCs) in a rat model of CSCI in acute and subacute stages was assessed. White Wistar rat were divided into control, sham-operated, CSCI untreated model, CSCI grafted with NESCs at 1 day after CSCI, and at 7 days after CSCI. Read More

Background: Decompressive craniectomy is a commonly performed procedure. It reduces intracranial pressure, improves survival, and thus might have a positive impact on several neurosurgical diseases and emergencies. Sometimes primary skin closure is not possible due to cerebral herniation or extensive skin defects. Read More

Aortic occlusion is used during trauma resuscitation for patients with profound shock and cardiac arrest. Aortic occlusion increases coronary and cerebral perfusion permitting time for interventions in an attempt to salvage moribund patients. Resuscitative endovascular occlusion of the aorta (REBOA) is a less invasive method of aortic occlusion and its indications are being defined, but it is used primarily for noncompressible torso hemorrhage.

Rationale: Spontaneous intramedullary spinal cord hemorrhage (hematomyelia) is a rare disease and most cases have specific etiologies such as cavernous malformations and tumor. Most reported cases are about surgical treatment of intramedullary spinal cord hemorrhage, but there are no reports of rehabilitation effectiveness reported. This case reports the first case with positive effect of rehabilitation on a patient with intramedullary spinal cord hemorrhage, who did not undergo surgery. Read More

Objective: Whereas open repair is the "gold standard" for most aortic arch diseases, a subgroup of patients might benefit from an endovascular approach. The introduction of branched stent grafts with dedicated design to address the challenges of the ascending aorta and the aortic arch has opened an entirely new area of treatment for these patients. We investigated the early outcomes of branched thoracic endovascular aortic repair (b-TEVAR) in various types of disease of the aortic arch. Read More

Purpose: The reliability of assessment of the artery of Adamkiewicz before the aortic repair is highly dependent on the display of the continuity of this artery with the aorta, mainly around the vertebral pedicle, by computed tomography angiography (CTA). We hypothesized that the sharp filter kernel can improve visualization of this continuity of the vessel structure because of its edge enhancement and high-spatial resolution. This study was performed to compare the subjective and objective image quality of spinal CTA reconstructed with sharp and smooth filter kernels. Read More

Background: Complicated operative vaginal deliveries are associated with high neonatal morbidity and maternal trauma, especially if the procedure is unsuccessful and a cesarean delivery is needed. The decision to perform an operative vaginal delivery has traditionally been based on a subjective assessment by digital vaginal examination combined with the clinical expertise of the obstetrician. Currently, there is no method for objectively quantifying the likelihood of successful delivery. Read More

Background: Spontaneous spinal epidural hematoma (SSEH) is an uncommon disease, but it can lead to acute cord compression with disabling consequences.

Background And Importance: Advances in minimally invasive (MIS) and mini-open surgical approaches have led to reductions in perioperative morbidity without compromising rates of resection of non-degenerative intradural spinal pathologies. Whether these approaches may be adapted for the surgical resection for intramedullary vascular malformations - such as cavernous malformations (CMs) - has yet to be reported. The authors describe a mini-open transspinous approach to resect a ruptured intramedullary CM of the conus medullaris. Read More

The RUNX1-EVI1 gene generated by the t(3;21) translocation encodes a chimeric transcription factor and is a causative gene in the development of de novo acute megakaryoblastic leukemia and leukemic transformation of hematopoietic stem cell tumors. Heterozygous RUNX1-EVI1 knock-in mice die in utero due to hemorrhage in the central nervous system and spinal cord and complete abolishment of definitive hematopoiesis in the fetal liver. On the other hand, the chimeric knock-in mouse develops acute megakaryoblastic leukemia. Read More

In humans, spinal cord injury (SCI) is often accompanied by additional tissue damage (polytrauma) that can engage pain (nociceptive) fibers. Prior work has shown that this nociceptive input can expand the area of tissue damage (secondary injury), undermine behavioral recovery, and enhance the development of chronic pain. Here, it is shown that nociceptive input given a day after a lower thoracic contusion injury in rats enhances the infiltration of red blood cells at the site of injury, producing an area of hemorrhage that expands secondary injury.

Background: Neurodegenerative disorders have a complex pathology and are characterized by a progressive loss of neuronal architecture in the brain or spinal cord. Neuroprotective agents have demonstrated promising results at the preclinical stage, but this has not been confirmed at the clinical stage. Thus far, no neuroprotective drug that can prevent neuronal degeneration in patients with neurodegenerative disorders is available. Read More

Intracranial dural arteriovenous fistulas (DAVFs) draining into the perimedullary venous system are rare and potentially life-threatening lesions often presenting as a myelopathy. The early and proper diagnosis of this rare disease is challenging because the symptoms are nonspecific. Acute clinical deterioration in patients with spinal DAVFs treated with steroid administration has been described. Read More

Background: Spinal epidural cavernous hemangiomas are rare vascular malformations. Exceptionally, they present with dumbbell-shaped morphology. When they happen, it's mandatory to include their pathology in the differential diagnosis because of their similarity to schwannomas. Read More

Spinal hematomas are a frequent indication for radiologic evaluation and can be a diagnostic dilemma for many radiologists and surgeons. There are four types of spinal hematomas: epidural, subdural, subarachnoid, and intramedullary (spinal cord) hematomas. Because they differ by their location in relationship to the meningeal membranes and spinal cord, unique radiologic appearances can be recognized to distinguish these types of spinal hemorrhage.

The topographical distribution of dural arteriovenous fistulas (DAVFs) was analyzed based on the embryological anatomy of the dural membrane. Sixty-six consecutive cases of intracranial and spinal DAVFs were analyzed based on the angiography, and each shunt point was identified according to the embryological bony structures. The area of dural membranes was categorized into three different groups: a ventral group located on the endochondral bone (VE group), a dorsal group on the membranous bone (DM group), and a falcotentorial group (FT group) in the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragma sellae.

Background: Castleman disease (CD) is an uncommon disorder of deregulated lymphoproliferation with unicentric (UCD) and multicentric forms based on extent of nodal involvement. Gross resection with histopathologic analysis remains the gold standard for diagnosis of UCD and is curative in most cases. Symptomatic paraspinal UCD is a rare presentation with potentially dangerous complications, and its tendency to mimic more common spinal tumors presents a significant diagnostic challenge. Read More

In adulthood, spinal cord MRI abnormalities such as T2-weighted hyperintensities and atrophy are commonly associated with a large variety of causes (inflammation, infections, neoplasms, vascular and spondylotic diseases). Occasionally, they can be due to rare metabolic or genetic diseases, in which the spinal cord involvement can be a prominent or even predominant feature, or a secondary one. This review focuses on these rare diseases and associated spinal cord abnormalities, which can provide important but over-ridden clues for the diagnosis. Read More

Background: Spontaneous spinal subarachnoid hemorrhage (SAH) is extremely rare and occurs in <1% of all cases of SAH. To the best of our knowledge, only 1 case of spontaneous spinal SAH with later development of a symptomatic spinal arachnoid cyst (SAC) has been described in the literature to date. The objective of the present study was to report the challenging clinical management of SAC based on a literature review. Read More

Background: Adamkiewicz arteries vasospasm in spinal cord subarachnoid hemorrhage (SAH) can affect the spinal cord. Although muscle dysfunction of extremities is a common problem after spinal cord ischemia induced by SAH, to our knowledge there are no studies on degenerative changes in peripheral nerves. We studied the histopathologic changes in sciatic nerves after spinal SAH. Read More
